Still encounter "TypeError: issubclass() arg 1 must be a class" problem with pydantic == 2.9.2 and scapy == 3.7.6

^{Originally posted by LuoXiaoxi-cxq September 26, 2024} I was running the training part of the [self-attentive-parser] (https://github.com/nikitakit/self-attentive-parser), where I met this error (probably caused by version problems of spacy and pydantic):

TypeError: issubclass() arg 1 must be a class

This issue says installing two packages chromadb and pydantic will work, so I installed them. I ran

python -m pip install -U pydantic spacy
python -m pip install -U chromadb spacy

I am running on Windows 11. Now, my environment is

Python == 3.10.14
pydantic == 2.9.2                   
pydantic-core ==  2.23.4 
scapy == 3.7.6
typing-extensions == 4.12.2
chromadb == 0.5.9 

However, the problem still exists. According to this issue, the problem ("TypeError: issubclass() arg 1 must be a class") should only exist for pydantic v1.10.7 and earlier related to the recent release of typing_extensions v4.6.0. My versions are higher, but this error isn't solved.
